After clashing for months in court filings, lawyers in the Mohamed Mohamud terrorism case will take their arguments over evidence before a judge this morning in Portland's U.S. District Court.

District Judge Garr M. King will hear them at 9:30 a.m.

Mohamud, 20, was arrested in an FBI sting Nov. 26, 2010, after he allegedly attempted to ignite a weapon of mass destruction next to Portland's holiday tree lighting ceremony in Pioneer Courthouse Square. The bomb, as it happens, was a harmless fake presented to Mohamud by undercover FBI operatives posing as terrorists.

King is scheduled to hold separate hearings on two defense motions today.

The first of the hearings will be on general evidence to be produced by the government and another on disclosure of FBI applications for warrants under the Foreign Intelligence Surveillance Act. The law, known as FISA, allows judges in a secretive court in Washington, D.C., to sign surveillance warrants in terrorism and espionage cases.
